Habitat and landscape features that influence the rate of interpatch
movement and colonization may determine the likelihood that a species will persist
in fragmented landscapes. We simulated patch extinction by removin ...

Off-highway vehicle (OHV) recreation impacts species and ecosystems around the world, and is particularly prevalent in the United States. Our study examines the impact of OHVs on one of several species restricted within ...

Policymakers are examining a wide range of alternatives for climate change mitigation, including
carbon offset sales programs, to enhance sequestration in the forest sector. Under an offset sales
program, on-the-ground ...

Most studies to date in the humid tropics have described a similar pattern of rapid translation of rainfall to runoff via overland flow and shallow subsurface stormflow. However, study sites have been few overall, and on ...

Small-area estimation (SAE) is a concept that has considerable potential for precise estimation of
forest ecosystem attributes in partitioned forest populations. In this study, several estimators were compared as
SAE t ...

We studied stand development in three distinct forest types in southwestern Oregon using six stands
each in uncut and clear-felled old-growth stands and nearby young stands (18 total). Old-growth stands
showed a wide r ...

Oregon’s forested coastal watersheds support important cold-water fisheries of salmon
and steelhead (Oncorhynchus spp.) as well as forestry-dependent local economies. Riparian
timber harvest restrictions in Oregon and ...

Swiss needle cast (SNC), an important fungal disease of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), has increased in severity throughout its natural and introduced range over the last half century. The role of cl ...
